Answer 2

Answer:

3 : 4

Step-by-step explanation:

$area \: of \: first \: triangle \\ = \frac{1}{2} \times h \times b \\ = \frac{1}{2} \times 5 \times 9 \\ = \frac{45}{2} \\ = 22.5 \: {cm}^{2}$

$area \: of \: second \: triangle \\ = \frac{1}{2} \times b \times h \\ = \frac{1}{2} \times 10 \times 6 \\ = \frac{60}{2} \\ = 30 {cm}^{2}$

A1:A2 = 22.5 : 30

$= \frac{22.5}{30} \\ = \frac{225}{300} \\ = \frac{3}{4}$

A1 : A2 = 3 : 4
